BOAT.

Specification of Letters Patent.

T0 all 'whomz't may concern:

Be it known that I, ANDREAS P. LUNDIN, a citizen of the United States, and a' resident of Bayside, borough of Queens, county of Queens, and State of New York, have in- .vented certain new and useful Improvements in Boats, of which the following is a specification.

This invention relates to improvements in boats, particularly adapted for use as lifeboats.

' rigid parts for the purpose of attaining additional security and to permit the rowing or sailing of the boat; and such adjustments maybe made substantially instantaneously and either while the boat is being loaded or during the lowering process, or while it 'is in the water or at any other suitable time.

' The preferred form of my invention comprises ,a metallic shell having a substantially i flat bottom and a well of oblong box-shape configuration, the sides of which Well are reinforced and kept rigid by the usual marginal and cross seats and in any other Well Y known way; a series of air-tight chambers or compartments between the bottom lof the boat or shell and the bottom of the Well, separated by vertical dividing partitions and the top of such air-chambers which forms the .bottom of the well and the floor of the boat being located above the water-line; when the boat is loaded to its full capacita series of bailing tubes communicating with the ioor of the boat and its bottom, each tube'having a reduced opening at lits upper end and be-V ing provided at suchiupper end- With a valve :n the form of a rubber ball adapted to close or seat on such reduced opening to keep out water but to open to permit water to escape from the well; a superstructure comprising rigid side and end members or leaves. hinged to the shell-plating and adapted to fold inwardly, the lineof folding or hinging being position;

substantially coincident or in the same hori' i zontal plane as the upper surface of the marginal and cross seats, and means comprising a series ofslotted and notched lock plates cooperating with locking rods attached at one end to the side and end members or leaves respectively, and having the other end bent to reciprocate in the slot when the side and end members are raised or lowered and to spring into and lock with the locking notches when such members are forced slightly be# vond their normal vertical positions. l also preferably provide what l shall term supplementary 'buoyant sides of balsa -wood which are connected to the flat sides of the metallic shell in any suitable. manner and lilound out the symmetrical lcontour of the oat.

In the accompanying drawings, in which similar reference characters designate corresponding parts throughout the several views, Figure 1 is a side elevation of a life-boat embodying my invention'and showing the superstructure folded down; Fig. 2 is a plan view of the boat shown in Fig. l, the superstructure being locked in upright or vertical Fig. 3 is a section taken through the' longitudinal axis of the boat showing the superstructure locked in upright or vertical position; Fig. 4 is a side elevation of two life-boats embodying my invention, one stowed on top of the other; and Fig. 5 is an enlarged cross-section of my improved lifeboat, the position of the second boat being shown in dotted lines.

Referring now to the accompanying drawings which illustrate a preferred embodi- :ment of my invention, A designates a shell of metal or other suitable material having a substantially flat bottom a and provided with a well or cockpit B, the space between the bottom a and the oor I) of the well B being divided into a series of air-tight compartments or chambers C by suitable dividing partitions 0. As illustrated, the Well B 1s rectangular in configuration and is provide at the extreme upper edge with cross seats E and marginal seats F whic together with the metallic flow of the well, assist in reinforcing the shell to form a structure of .great strength and rigidity. A series of suitable tubes D preferably connect openings in the ioorof the well and the bottom of the boat. The communicating opening Ibetween each of tubes and the floor b is preferably no Patented May 25,1915.v

sired, the shell A may be further reinforced or stiHened in any well known manner without interfering with the folding of the Superstructure as hereinafter described.

A protective superstructure, comprising rigid side members G and end members G',

`is connected to the shell plating at the sides and ends of the rectangular well and is adapted to be raised and lowered relatively to the shell. Obviously when the side and end members Gr Gf are raised relatively to the shell, they form a superstructure which will prevent the boat from being Hooded with water and will protect the occupants thereof from wind, waves and spray in rough weather, and when such side and end members G G are lowered relatively to the shell a plurality of such boats may be readily stowed or nested one on top of the other on board ship and under davits. As illustrated, the side members Gand end members G are hinged by means of hinges g3 to the shell plating and are adapted to be folded inwardly and to rest on the seats of the boat when the boats are-not in use and it is devsired to 'stow the same one on top of the other. Means for automatically locking the side and 4end members when the same are moved into vertical position is preferably provided, such means preferably comprising a series of lock plates g', the plates for the side members G being secured vto the sides of the cross seats E and the plates for the end members G being secured to the 45- sides of the marginal or'side seats F. Each lock plate g is provided with a horizontal slot gs and a locking notch g2; a locking rod g is connected at one end withthe upper edge of one of the members G G and its other end is provided with a bent portion which extends within and is adapted to reciprocate in such slot g'? during the raising and lowering of the members G G', and to lock with the locking notch g2 which extends downwardly and rearwardly from the end of the slot g2 nearest to the members G G', so that when a member G or G is raised to its eXtreme upright or vertical position and then sprung back slightly beyond its normal vertical position, the bent portion of the rod 'will spring into the locking notch and the member G or G', as the case may be, will be securely and automatically locked in vertical or upright position. I also preferably provide each of the members GreG' with a stiffening rib g5 which, when such members are in vertical position, tend to reinforce the same but when such members are in their folded 'or lying down position the ribs g5 serve as a somewhat elevated support or cradle for stowing another similar boat on top thereof and leave room between the seats of one boat and the bottom of the next to stow oars, masts, swords andother accessories.

Another feature of my invention is the provision of a -rigid metallic shell 'having flat sides with what I shall term supplementary sides of highly buoyant material and preferably of balsa wood. I preferably so form such supplementary sides as to round out the contour of the boat. These supplementary-sides may be secured to the metallic shell plate by lashing the same to the sides of the metallic shell or in any other suitable manner, and will not only materially add to the strength and'stability of the lifeboat but`will serve as fenders or l guards to prevent injuryto the boat in the event that it b e bumped against the vessel in launching. Balsa wood when properly treated to close its pores is highly buoyant and -will have substantially the same degree of buoyancy as would for instance metallic air-tight compartments of the same size, and furthermore in view of the fact that these supplementary sides do not form an integral part of the hull proper they may be ground to pieces or entirely destroyed by impact with the sides of the vessel without Vin) uring the water-tight qualities of the boat. Y

I furthermore preferably provide my improved boat with any well known disengaging gear such as I have designated K, a manhole for drinking water and supplies, which I have designated L, and the upper edges of the side members G are provided with oar-locks or notches g4 to permit the rowing of the boat. I also preferably provide removable lee-boards or swords I, which lact as means for permitting the boat to be properly handled when it is desired to steIpI a mast therein and sail it.

aving described my invention, I claim: i

l. A lifeboat comprising a metallic shell having a well, polygonal in conformation,

'air-tight compartments beneath the well,

marginal and cross seats connected to the shell at the upper edge of the well, asuper- Y structure composed of rigid side and end connected to the amidship section outer sides of the metallic shell to round out the contour of the boat, add to its stability and serve as fenders.

3. A lifeboat comprising a metallic shell having a' well, polygonal in conformation, air-tight compartments beneath the Well, marginal and cross seats connected to the shell at the upper edge of the well, a superstructure composed of side and end members hinged to theshell and adapted to fold inwardly, a stii'ening rib on each side and end members for reinforcing the same when in raised position and serving as an elevated support for another boat when in folded po-l sition, and means for automatically locking such side and end members when the same are moved into raised position.

4; A boat embodying a rigid metallic shell comprisingv rounded fore and aft sections and an amidship section provided with a well polygonal in conformation and having flat sides, and supplementary sides composed of balsa Wood having its pores closed against the admission of waterand attached to said flat outer sides to round out the oontour of the boat, add to its stability and serve as fenders.

5. A lifeboat embodying therein a metallic shellhaving a well polygonal in conformation, air tight compartments beneath the well, a superstructure composed of side and end members each of which is rigid over its entire surface and is hinged to the shell to permit raising and lowering thereof and means for automatically locking such side and end members when the same are moved into raised position.

In witness whereof, I have signed my name to the foregoing specification inthe 4o presence of two subscribing witnesses. f
